Subject: [PATCH] media: venus: dynamic handling of bitrate
Date: Wed, 31 Oct 2018 13:12:08 +0530	[thread overview]
Message-ID: <1540971728-26789-1-git-send-email-mgottam@codeaurora.org> (raw)

Any request for a change in bitrate after both planes
are streamed on is handled by setting the target bitrate
property to hardware.
